Refreshing Your Fuel Cell

Experiencing reduced power of your fuel cell? If the power of your fuel cell drops off after some use, which is seen as a reduction in the torque of the motor, it is desirable to exchange the distilled water and draw in fresh water with the syringe.
This is especially true when the fuel cell has not been used for a considerable time. Several consecutive charging and discharging procedures will also improve the power capability of the fuel cell. To do this, it is best to disconnect the wires to the motor and discharge the fuel cell through the multimeter
set for the 10 A range.
A reduction in power can also be caused by too low of a compression of the fuel cell module. The nuts can be carefully tightened with an 8 mm hex wrench which you turn to the right to increase pressure.
Caution! Tighten the nuts carefully so you do not damage the threads.
